Description of the Instrument |
|
The device is designed to produce emission spectra, excitation spectra, measurements of the lifetimes of excited states, to study the molecular dynamics in solution. Double monochromators in the excitation and emission channels, heavy duty xenon lamp as the light source and the detection system operates on the basis of accounts of individual photons, can achieve the unique sensitivity and signal/noise ratio. Device equipped with fluorescence lifetime measurement based on time-correlated single photon counting (TCSPC). It can measure luminescence decay from 0.1 ns to a few seconds. |
